In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
Hello gentleman, I'm looking for some insight on a hydronic issue. I'm responsible for maintaining several large office buildings in Detroit area. One of which has single pipe perimeter baseboards along the entire curtain wall. every zone is 75' long, 5 per exposure per floor for a total of about 80 zones. every zone has a sliding expansion coupler just before entering the return line. here lies the issue. many of the expansion couplers are starting to leak due to age. Ive had 5 leaks this season alone. these couplers have a threaded packing gland I've been able to tighten to stop leaks temporarily. I've reached out to the original provider AMTROL who quit selling these many years ago. They suggested I contact SLANTFIN who had been their supplier, same story no longer available. Ive search on line and thru all my local sources with no luck on suitable replacements. Ive been told to just remove them and not to worry about the expansion which according to my calculation should be in excess of .67in heating from 75f-150f. I'm skeptical that this would be o.k. Any insight from the experts would be helpful.
